To all @Dhotit mdy'concem:

Be 1t' .lmownythatfwa VILBER C. LEGG,

BYRON` S. L'ncmand BENJIMAN C. Dir-HON,

citizens ofthe United States, residing at windfall, 4the ycounty of Tiptonv and State of Indiana, have invented anew and useful'lmprovement in Corn Snapping and Husking Machines, of which the following is a specification.`

This invention relates to a device for snapping ears. oiV corn from the stalks, huskingfthe earscand'jconveying the ears of corn -to .j wagontraveling by the side of the device, f and to which. the said device is connected 'n any suitable manner, and another `obje t of thefinvention/ is a device of this lnd .inv which any of the corn which may .become shelled during the husking will be saved and also conveyed to the wagon.

' The invention consists of a wheeled frame provided upon its front with two pairs of guidfy plates, each `pair of plates being adap d" to operate upon a row of corn so that ears aregathered from two rows at the same time. `To the rear of each of said 1 guide plates and. the v.mechanism carried by them is arranged a pair of snapping rollers between which the stalks pass and which snaps the ears from the stalks and deposits the same upon husking rollers.

The invention consists also in providingendless `chains having .ngers .which work betweenthe husking rollers of eachpair and conveys the ears of'corn to an elevator carried at the rear of the device which receives the shown in the accompanying drawings, yinl which, v

Figure 1 is a top plan view. Fig. 2 is a side'elevation. Fig.v 3 is a front elevation. Fig. 4 is'a rear elevation. Fig. 5 is a detail section onthe linef'5-5 of Fig. 6. Fig-6 is a top plan' view of one set of snappingrollers, looking from the line 6-6 of Fig. 5.

i Fig. 7 is asection on the line 7--7 of Fig.

6. Fig. 8 is a detail perspective view .of a portion of the front of the frame. Fig. 9

is a'detai'l sectional view showing th'eman- 'nery of llocking an adjustable front fork.

Fig. 10 is a detail view partly in section of a clutch. F ig.l 11 is a detail view showing the manner ofjournaling the husking rollers. Fig. 12 is a cross-section through the body portion of an inner snapping roller. Fig. 13 is a slmilar section through an outer snapping roller. Fig. 14 isva detail sectional view showing the manner of journaling the lower end of a snapping roller. Fig. 15 is a plan view of a portion of a chain belt.

In these drawings v1 represents the frame of our cornv gathering device which lframe carries stub axles 2 upon which aremounted suitable supporting wheels 3 `'provided Iwith adjusting mechanism 5 for raising and 'flowering the frame, which mechanism is now 1n use upon harvesters of thel Mc` Cormick type. The wheels 8 are provided v with sprocket wheels 6 which by means of suitable sprocket chains 6a, and sprocket wheels 6b, transmit rotary motion to a main 'power shaft 7 upon -which are mounted bevel gears 8. Upon the frame 1 and adjacent opposite sides are mounted forwardly and downwardly inclined l snapping rollers 9 and 10. These snapping rollers will be described in detail hereafter.

The snapping rollers 9 areprovided with `gears 11 which mesh with'a gear '12 carried 13a. Arranged centrally upon the frame 1 vand between the snapping rollers are a` pluralitv of husking rollers 14 arranged in sets orcpairs.' While the number of these rollers may be varied with the size of the machine, we have illustrated a construction in which each set of husking rollers consists of two pairs. These rollers are corrugated or l'uted and are arranged parallel to each other and slightly apart. Atl their rear ends the husking rollers are reduced and provided with gears 16, the gears of each pair meshing with each other. These husking rollers are journaled in fixedk boxings 17 and in slidable boxings 18, one roller of leach pair being journaled in a fixed boxing and one in a slidable boxing and the said boxings are also arranged in pairs, each pair consisting `of a ixed and'a slidablefboxing which are connected by a` spring 19.: .Byrd means of this construction each pair of husk" ing rollers has falso a limited amount of l movementaway from each othersothat they can adjust themselvesas the work i'nay' require.. A

Uponthe front of the device'and in alinement with the snapping rollers are arranged in pairs slightly'divergent lguide plates 20 which are provided with inclined shafts 21 which carry upper and lower sprocket wheels l -22 over which runs sprocket chains'23 which carry fingers 24 and which run over idlers 25 mounted at the ends of the guide plates 20. Thesejfngerstravel lengthwiseof the guide platesand upon their inner adjacent faces .travel rearwardly, thus picking up and conveying to the snapping .rollers all stalks which mayhave fallen or may be bent over out of reach-of the snapping rollers. Upon the lowerend of each of the snapping rollgearQ which meshes with ers 10 is fixed a a. gear '27 carrie by theadjacent vertical shaft 21,1s'o that thev saidfshafts. are drivenbyfthe outer lor1 larger @snapping rollers.

.'Ifransversel front and rear shafts 28 are carried also by the upper portion .of the frame 1, and upon these shafts. are arranged liusking. rollers 14 of each pair. These pins' *sprocket wheels 29 overwhich ,run sprocket chains' 3() which chainsoarry pins or spurs 31 whichoverhang the space between the travel rearwardly andthus convey fthe corn f toward the rear Lof the frame and vprevent the saine from collecting-at the forward end. The main power shaft 7 has a sprocket wheel 32 over whichl runs a chain 33 which also passes over the sprocket wheel 34 on the rearl shaft 28. Agt .the rear of the frame 1 is ar*-- ranged a' chute 35 inwhich works an endless kchain-36,the'chute and chain forming an elevator which receives the ears and conveys them upwardly and downwardly ldischargl. provided with a -bevel pinion 37. 'which ing them into the wagon. a

One of each pair of the lhiisking rollers is j meshes with a'bevel gear-38 on a powershaft 39. This shaft is provided. with a sprocket -wheel 40 over which runs a chain141 which also runs over a sprocketwheel 42-onA the shaft 7. The fr nt portion of the frame .between the gui e plates 20 is 4supported by 'a suitable vfront wheel 43. This wheel 43 is mounted in a, yoke 44 adjustably held in a bearing-in the frame frontybar by means lof a yoke stem^45 `perforated at'46 to re`l ceive a pin 47 held in -VA place by a spring 48.

l'The bearing is preferably a long sleeve 50 to which is pivoted-'a lever 49. The sprocket wheelsefbare loose on the shaft .7 and are lockedtothe shaft by the usual clutch mech-y anism asfshownat 51.*'

)Referring to the snapping rollers i 9 and l 10fthelower portions of these rollers are' in the :form of screws l.5 4. 'l screw@ por- -spring 4S, thus withdrawing the pin. 47 and,

tion entends-far enough to vpass thefstalks 'l beyond the idlers 25 'and insure positive feed of the stalks to the rollers. The ex treme end portion ofl each snapping 'roller is smooth, thereby avoiding one objection made to devices employing such rollers, viz.: that they uproot the stalks. The interme diate main body portion of the' rollers is iiuted spirally. Up to this.point both the -rollers 9 and 10 are of like construction.

But in addition to the iluting the rollers l()v are spirally grooved, as. at- 4while the lrollers 9 are'provided withvs'pirally arranged blades 56. Both the grooves 55 and blades. 56 are of a different pitch'from the flluting. To aid in .lifting fallencornand especially stalks which have fallen 4at an angle to the roller, shafts 57 "are carriedto the front. of the frame, and extenddownwardly, 4sai-il .shafts being arrangedy uponeach side,.of

the pairs of snapping rollers and at their Vlower ends are provided with spirally arranged blades=58 and adjacent said blades arearrangedf parallel -oct'agonal vrollers 59, a fsaidrollers being mounted in a plane above' the guides 2O.I The blades 58l yandilrollers 5 9 aid materially in lifting up and carrying intoV proper position the fallen stalks. ,As

some. of the corniwill become/'shelled in the liusking operation we provide common means for discharging the husks at the ety front of the machine and for collecting the y shelled'corn and discharging the saine into the elevator at'V the rear of the machine a solid bottom 60 -is provided beneath the liusking rollers, and between the said rollers and over this body travels lengthwise of the l machine an endless chain belt 61 which belt receives the husksand discharges them at the front end of the machine. The shelled corn drops .through the links ofthe belt upon the bottom 60 and as the lower portion ofthe belt -travels rearwardly transverse ribs 62 carried by the belt pass overV the bottom 60 and convey the shelled corn to the elevator .by means of which itis conveyed with the ears to the receiving wagon.

In order -to drive the shafts 57 hereto- .fore described they are provided at their upper'ends with bevel gears G3 which mesh -of .the stalks ofcorn for-which they are l working. The frontof the frame 1-'can bevertically adjusted by shifting the lever 49 which passes througlw *he slot in the permitting the yoke stem 45 to be readjusted in the sleeve 50 when the ;pin can be inserted in another perforation 46.

lVhat we claim, is:

1. 'In a device of the kind described, snapping rollers arranged inpairs, said rollers extending upwardly and rearwardly, the lower portions of said rollers being screw shaped, the upper end portion of each roller being smooth andthe intermediate portionbeing sprally uted, one roller of each pair' being also spirally grooved' an the other y.roller of the pair being provided-'with a spirally arranged blade cooperating with the groove of the other roller of the pair, said blade and groove having a different pitch rorn the luting.

2. A corn harvesting machine comprising two pairs of upwardly and rearwardly 'in- .elined snapping rollers arranged parallel operating roller and registering with-V said groove, the said blades snapping Athe ears,

the outer 'rollers being of greater .diameterf' than: the inner rollers, each pair of rollers directing the ear into the space between the two pairs of snapping rollers.
